Vascular device

Abstract

The present disclosure is directed to a vascular device comprising a catheter and a structure as well as a movable macerator. The structure is provided at a distal part of the catheter and comprises a disengaging portion configured to disengage vascular debris from a vessel wall, and a collecting portion configured to collect removed vascular debris. The movable macerator is located at least partially within the structure and/or proximal to the structure and configured to macerate removed vascular debris, so that the device is configured to macerate vascular debris by way of movement of the macerator for facilitating entry into the opening and/or conveyance through the lumen.

1 . A vascular device comprising a catheter having a lumen for conveying vascular debris, the lumen having an opening for receiving the vascular debris, the catheter defining a longitudinal axis, the device further comprising:
 a structure provided at a distal part of the catheter, the structure comprising:
 a disengaging portion configured to disengage vascular debris from a vessel wall, and 
 a collecting portion configured to collect vascular debris, and 
   a moveable macerator located at least partially within the structure or proximal to the structure, the moveable macerator located distal to the opening and configured to macerate vascular debris.   
     
     
         2 . The vascular device of  claim 1 , wherein the structure is expansible and compressible. 
     
     
         3 . The vascular device of  claim 1 , wherein the macerator is rotatable around the longitudinal axis. 
     
     
         4 . The vascular device of  claim 1 , wherein the macerator is axially moveable in the direction of the longitudinal axis. 
     
     
         5 . The vascular device of  claim 1 , wherein the macerator ( 8 ) is expandable in a radial direction substantially perpendicular to the longitudinal axis (A). 
     
     
         6 . The vascular device of  claim 1 , wherein the macerator ( 8 ) comprises at least one of a hook and angled bar, and/or has at least one of a ring-shape and a star-shape. 
     
     
         7 . The vascular device of  claim 1 , wherein the structure ( 4 ) comprises struts ( 7 ), optionally representing a stent-like configuration. 
     
     
         8 . The vascular device of  claim 7 , wherein the disengaging portion comprises a first region of struts and the collecting portion comprises a second region of struts, wherein the first region of struts differs from the second region of struts. 
     
     
         9 . The vascular device of  claim 8 , wherein the first region of struts is less dense than the second region of struts and/or struts in the first region of struts are further spaced apart from each other than struts in the second region of struts. 
     
     
         10 . The vascular device of  claim 8 , wherein the first region of struts comprises struts having leading edges. 
     
     
         11 . The vascular device of  claim 1 , wherein the collecting portion comprises a basket and/or has at least partially a substantially cylindrical shape. 
     
     
         12 . The vascular device of  claim 1 , wherein the disengaging portion at least partially comprises a conical shape. 
     
     
         13 . The vascular device of  claim 1 , wherein the structure is tethered to the distal end of the catheter. 
     
     
         14 . The vascular device of  claim 1 , wherein the macerator is configured to be actively moveable by way of ultrasound-drive and/or rotation of a driving bar/wire. 
     
     
         15 . The vascular device of  claim 1 , wherein the catheter comprises, in addition to the lumen for conveying vascular debris, a lumen for receiving and/or handling the structure and/or the macerator. 
     
     
         16 . The vascular device of  claim 15 , wherein the lumen for receiving the vascular debris and the lumen for receiving and/or handling the structure/macerator are arranged coaxially or offset to each other. 
     
     
         17 . The vascular device of  claim 1 , wherein a membrane is provided in and/or over the collecting portion and/or distal to the collecting portion.
